 The differences in strength can be very significant. For instance, gross measures of body strength suggest that women are approximately only 50% to 60% as strong as men in the upper body, and 60% to 70% as strong in the lower body.<ref name="pmid8477683">Miller AE, MacDougall JD, Tarnopolsky MA, Sale DG (1993) [https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=8477683 Gender differences in strength and muscle fiber characteristics.] ''Eur J Appl Physiol Occup Physiol'' 66 (3):254-62.
